は、私は多くの場所が答え が最初ありがとう発見していない見つける

public static void sendOldHttpRequest(final String address, final IHttpCallbackListenet httpCallbackListenet) { 
    new Thread(new Runnable() { 
     @Override 
     public void run() { 
      HttpURLConnection urlConnection = null; 
      try { 
       Log.i("tzf", "run: "+address); 
       URL url = new URL(address); 

       urlConnection = (HttpURLConnection) url.openConnection(); 
       InputStream inputStream = urlConnection.getInputStream(); 
       BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream)); 
       StringBuffer response = new StringBuffer(); 
       String line; 
       while ((line = reader.readLine()) != null) { 
        response.append(line); 
       } 

       httpCallbackListenet.onFinish(response.toString()); 

       reader.close(); 
       inputStream.close(); 

      } catch (Exception e) { 
       httpCallbackListenet.onError(e); 
      } finally { 

       if (urlConnection!=null){ 
        urlConnection.disconnect(); 
       } 
      }

Answer 1

HttpURLConnectionは、400以上のHTTPステータスコードに対してFileNotFoundExceptionをスローします。 getResponseCode（）を使用すると、コンテンツを読み取る前に応答ステータスコードを確認できます。多分あなたの要求は悪いですか？または、要求されたリソースへのアクセス権がありません。あなたはこの

InputStream inputStream; 
int responseStatusCode = urlConnection.getResponseCode(); 
if(status != HttpURLConnection.HTTP_OK) { 
    inputStream = urlConnection.getErrorStream(); 
    //Get more informations about the problem 
} else { 
    inputStream = urlConnection.getInputStream(); 
}
